I got a doe last night also.
I was using a 250 grain,T/C shockwave bullet,90 grains of 3fffg goex blackpowder,range 110 yards,Knight wolverine.
Dang bullet didnt expand one bit,just the little plastic tip broke off,found it under the hide on the far side,shot was a bit high,took out the arteries that run along the underside of the spine,DRT,but no expansion at all.A double lunger ,it would have sailed on through.
I didnt think I was getting much velocity,maybe 1500 fps or so,gonna have to check that.
